Born in 1058 in Tus, Khorasan, in present-day Iran, Abu Hamid al-Ghazali was one of the most original thinkers the world has known. Besides being a major influence in the Muslim world, the West has also felt his effect. He influenced major figures of medieval philosophy such as Thomas Aquinas and Moses Maimonides, who shaped the philosophy of the Latin West. As the author of some 250 books on topics ranging from theology and ethics to metaphysics and philosophy, al-Ghazali came to be known as 'Proof of Islam'. For almost a thousand years he has served as an inspiration for spiritual seekers everywhere as he was someone, like the Buddha, willing to give up everything: wealth, position, family and comfort in order to search for Truth. This film sets out to discover who al-Ghazali was and whether we, living in the 21st century, can still find relevance in his teaching.
